AMST offers Liquid fuel HVOF spray coating system “MACHJET-II” to spray coating powders like all powders from Tungsten carbide family, metallic, self-fluxing, etc to offer high wear, erosion, cavitations, etc resistant coating on the surface. Offered “MACHJET-II” HVOF system is designed to work with Liquid Fuel (Aviation Grade Kerosene K2) and Oxygen. The offered system is mostly use for automatic / robotic HVOF coating application and thus considered as high level of HVOF coating requirements for any job shop / OEM applications.
The offered MACHJET-II HVOF system consists of MACHJET-5K HVOF gun, Rotameter type control panel MJ-6600, Volumetric feed powder feeder MFD-3500 which is similar to Tafa Praxair’s 1264 , Gas control unit and portable trolley. The offered HVOF gun MACHJET-5K is equivalent to is equivalent to Tafa Praxair’s JP-5000 / 5220 HVOF spray gun. .
The model AMST HVOF system MACHJET-II sprays carbide powders melts in the HVOF gun MACHJET-5K due to combustion takes places in the gun by Oxygen & Liquid fuel for spraying molten material on the substrate thereby generating high quality & dense coating on the surface.

The HVOF spray process efficiently combusts oxygen and liquid fuel to produce high kinetic energy with controlled heat input. The coating material, in powder form, is introduced into the flame and uniformly heated by the hot gas stream to a molten or semi-molten condition. The flame and powder are accelerated by a barrel to produce supersonic gas and particle velocities, which propel the powder particles toward the substrate to be coated.
